Simply put, some early blocks aren't very good & some late ones check out fine and vice versa. As suggested previously have it sonic checked if you want to be sure. Otherwise limit the overbore to .030 and hope for the best. One minor point, on early [ '71-'75 ] blocks the main bearing bolt holes are blind. Later ones are open and possibly [?] that area may not be as strong.
